Sabine is a French assassin for hire, who works for diamonds as her payment. Sabine was known to be affiliated with Kurt Hendricks, as she has apparently worked for him in the past, but it can be assumed that the two never met face-to-face prior to their arrangement at the Burj Khalifa, as Hendricks posing as Wistrom did not notice that IMF agent Jane Carter had in fact replaced Sabine.
